For any wireless communications antenna system becomes indispensable. In this paper we analyzed linear array, planar array and three - dimensional (3D) array antennas. The array systems are simulated in Matlab based on uniform linear array antennas. Comparisons between planar array antenna and 3D array antenna are provided take into account different phases(More)
– One of the most challenging problems in high-rate data transmissions is to combat the inter-symbol interference introduced by the multipath propagation. Since adaptive equalization in time domain proved oftentimes to be a too expansive solution in terms of computational complexity and implementation costs, some different equalization approaches must be(More)
In this paper, a triple binary turbo codes (TBTCs) family with rate 3/4 constituent convolutional codes of memory 4 is presented. With an observer canonical form implementation of component encoders, the family has over 500,000 units. In this family, we addressed the issue of selecting turbo codes. Through an exhaustive search using a selection criterion(More)
In this paper, a comparison between radiation pattern characteristics for planar array and three - dimensional (3D) array antennas are provided. The systems are implemented in Matlab, starting from a linear array antennas. Simulation results using different numbers of antenna elements for planar array and three - dimensional array antenna are compared.
In recent years, adaptive signal processing has been applied to a variety of areas, ranging from acoustic applications to telecommunications networks. The concept of “smart antennas” is based on the use of this technique in antenna systems processing. Smart antennas have been considered as a key technology to provide the services demanded by(More)
– The resolution of a signal direction of arrival (DoA) estimation can be enhanced by an array antenna system with innovative signal processing. Super resolution algorithms take advantage of array structures to better process the incoming signals. This paper explores the eigen-analysis category of super resolution algorithm. The MUSIC (MUltiple SIgnal(More)
